4-in-1 OutputThe 4-in-1 output offers light ON and/or dark ON output(s) in which each automatically detect the

connected load, so the output either sources or sinks current depending on the load. A single sensor can operate as NPN light ON, NPN dark ON, PNP light ON, or PNP dark ON, reducing inventory costs and minimizing wiring time.
